Sources close to Burns today told MMAjunkie.com (www.mmajunkie.com) that the Iowa-based fighter has agreed to be a late replacement at next weekend’s pay-per-view event.

UFC 85 takes place June 7 at the 02 Arena in London, England.

The reason for Chonan’s likely departure from the card isn’t immediately known. However, if the fighter swap does take place, it would be the latest of numerous changes that have plagued the fight card since it was first announced. Chuck Liddell, Mauricio “Shogun” Rua, Chris Leben and James Irvin have all been scratched in recent weeks, and the televised main card has been in a constant state of flux.

Burns, who boasts solid Brazilian jiu jitsu skills, has posted stoppages in all five of his career victories — three by way of submission. Recently, he’s competed for the Victory Fighting Championships and Glory Fighting Championships organizations. In fact, earlier this month, he knocked out Bobby Voelker for the VFC interim welterweight title.

Although he’s a relative newcomer on the professional scene, Burns fought a number of times as an amateur. He is reported to have delivered UFC veteran Josh Neer the only loss of his amateur career.

Carneiro, a member of the Florida-based American Top Team, most recently defeated Tony DeSouza at UFC 79 to push his UFC record to 2-1. The 30-year-old’s only loss in the octagon was to top welterweight contender Jon Fitch.
